Lug Nuts Overtightened and NOW STUCK
 

Hi All- My local Porsche shop over tightened my lug nuts and I have tried everything to get them off. Heat, breaker bars, shop impact wrenches after heat applied ect.

I finally decided to just get a 19mm saw and drill them off...so i thought. I now have only one nut off, the rest are snapped and there is a little metal left that is holding the wheel to the car. See pics.

Any thoughts on how to fix this? Can't believe that paying thousands for brakes a few years ago would have caused so many headaches when i went to go get new tires.

call the Service Mgr. there and see what he says

better yet send an Email so you have a record ...

Nuts.
 

Sorry,

Don't see pics.

I am guessing there is corrosion between the lug and wheel. Did you try liquid wrench, or equivalent?

I recently did something similar on someone's KIA where we were able to drive the studs back in enough to loosen what was left of the nuts ...

Not ideal but if they're aluminium lugnuts it might work , best case scenario is you won't damage the rims as compared to trying to cutt of the remains of the nuts with a dremel !
I used a 4X air riveting gun with a large brass snap connected to a 3/8 air hose with 125 lbs air pressure.

Anti-seize lubricant........
 

I don’t see any trace of anti-seize lubricant on any of the lug bolts (?). What a nightmare you got there. Be careful not to ruin the wheels. Hope you succeed with minimal damage on that wheel. BTW, how many wheels are stuck?

Use the hole saw gently to get rid of the rest. Back off when they are through, then use a sharp point punch to get the remains off the studs. No other choice really. done lots of them, GRRRR.

Next time, don't go to extraordinary means. Instead, take a pic of the wheel, drive it back to shop, talk to the manager/supervisor/owner, tell them you want it to look just like it did when you dropped it off and let them deal with it. The pics are important in case they screw up the wheel.

They’re corroded, not overtightened...

I put on some recently sandblasted and powder coated aluminum lug nuts on, no anti-seize.

6 months later after rain and some car washes, took a huge breaker bar to get them off...

Aluminum, steel, and rain, don’t play well together...

your local Porsche shop seems unfamiliar with the TSB on lug nuts put out by Porsche

I would keep going with the hole saw as you have a remainder of one left to gauge how far to go before contacting wheel. I would even go so far as to put some other lugs on with a 1/8 inch or so distance from remainder and do some slow figure eights, stopping often to check. Everyone seems to think the nut in good condition is going to back off/fail (they won’t). If there is a next time, stop before you get this far!

Too bad there’s no such thing as a left handed holesaw...

Good point, but there's one that's close, with the diamond teeth on it used for granite and stone. But I don't know if they come in 3/4".

3/4" is readily available along with any number of other sizes.

Ugh. Nightmare! Looks like there is (was?) a factory hole saw tool for this application...

anti-seize is a must, but I've never seen a shop use it on lug nuts/bolts.

anti-seize and they will never be stuck and never fall off.

You don't need their flunkies doing any more damage. Best take your time.

Anyone ever use the candle wax and lighter trick? I've only seennit on YouTube. Melt some wax and let it drip onto the threads. Supposedly the wax works its way in between the threads and voila, what was stuck is no longer unstuck.
